Coach John Harbaugh said the decision to scratch Carr – who started all 16 games at cornerback last season – was based on the need to activate six defensive linemen against Houston running backs Arian Foster and Ben Tate.
“[N]ormally Chris is up,” Harbaugh said Monday. “Obviously, Chris is a big part of what we’re doing, especially when we play teams that throw the ball a lot. So that could be a big factor this week. We put an extra defensive lineman up this week because of the type of offense we were playing. Special teams was a part of that decision, too.”
